Any boost-converter design will have a practical limit to how much it can step up a voltage from input to output. Pulse-width modulation (PWM) controllers have timing limits that restrict the minimum ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...

Selecting a PWM controller has become less straight forward as leading edge DSPs, FPGAs and CPUs run on increasingly lower supply voltages and consume higher current. Sub 1V voltages are becoming ...

National Semiconductor has launched an integrated controller-driver chipset for high-voltage power conversion applications. This current-fed push-pull pulse-width modulated controller LM5041 works ...
